The river is not situated at 0 level altitude in the DEM and hence i cannot just do a simple raster calculation which takes all areas belore 12 meters. I want to figure out the areas in which there can be a 12 meter rise in water level using the river as the base from which the 12 meters will be made. (Ie the a certain pixel of the river can be at 15 meter altitude and hence i want the areas away from the pixel which will get a 12 meter increase in water levels).&nbsp;</P><P></P><P>Thank you&nbsp;</P></BODY></HTML> Wed, 18 Sep 2019 21:48:28 GMT goodone 2019-09-18T21:48:28Z Raster calculate based on altitudinal values of a river section - ArcMap https://community.esri.com/t5/community-development-questions/raster-calculate-based-on-altitudinal-values-of-a/m-p/791000#M35 <HTML><HEAD></HEAD><BODY><P>Hello,&nbsp;</P><P></P><P>I want to know how I can model the elevation of a 12 meter rise in water levels from a river on ArcMap.
